Joists made from composite or plastic

Size of joist:  (W)60 x (D)40 x (L)3000 mm

This innovative joist is made from wood polyethylene composite for strong and easy support to the deck.  Adequate ventilation and drainage are required to maximize composite decking performance. With these joists, you can build with the confidence knowing that the supporting structure is resistant to termites, splinters and decay. Enjoy the ease of a ground level deck with the confidence that a composite substructure can provide.

Plastic Joist

Size of joist: (W)100 x (D)50 x (L)3000 mm

This is made from recycled plastic, is solid, strong and will never rot. For those who want total peace of mind.

These are ideal for use on flat roofs, concrete or tarmac etc.  Using this system creates a moisture barrier between deck and ground, keeping the supports off ground which helps prevent rotting. Usually, around 8 batten fixers per sqm is required (exact quantity depends on weight of deck).
